INVALID-CHAIR.

Specification of Letters Patent. Patented Sept. 3, 1918.

Applieation'filed February 16, 1918. Serial No. 217,717.

To all whom it may concern:

Be it known that 1, JAMES ELLIMAN, sole proprietor of the firm of Elliman, Sons, Limited, of Slough, Buckinghamshire, England, a subject of the King of Great Britain, residing at 6 Queens Gardens, Hove, Sussex, England, have invented new and useful Improvements in Invalid-Chairs; and I dov hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use I the same.

This invention relates to invalid chairs, and has for its object to provide a chair in which the seat is of a sufficient depth from front to back to support the legs, as far as the knees of the occupant, in a raised or practically horizontal position when seated therein, and in which means are provided for drawing the seat backward and forward with the patient thereon so that relief is afforded the nurse or attendant in placing the patient upon, or removing him (or her) from, the chair, as occasion may require.

In carrying my invention into. effect I make the chair with a seat of sufficient depth to allow of the occupant being seated therein with the legs to the knees supported practically in the horizontal position, an independent support for the calves of the legs and feet being provided which is moved into position when required, and, to facilitate the placing of the patient in such position and of withdrawing him (or her) therefrom, I place over the ordinary fixed upholstered seat a pneumatic cushion attached at its sides (front and back) to cords the ends of which are connected to rollers fixed on the spindles of a chain and sprocket, or equivalent, gearing mounted upon one side of the chair and the working of which draws the cushion, and with it the occupant, backward or forward to suit requirements. For instance, when it is desired to place the patient in the chair, the gearing is turned by means of a hand wheel provided and the rear part of the cushion is brought sufficiently near the front edge of the chair to permit of the patient being easily seated thereon. The front end of the air cushion will then depend over the front edge of the fixed seat, and, being connected by the cord to the rollers on sprocket wheel spindle, be drawn under the chair free of the legs of the patient, who,

when seated, is with the traveling air cushion drawnbackward on the chair by a reverse movement of the sprocket or like gearing, until fully occupying the chair with his (or her) legs raised to a'comfortable positlon.

An auxiliary back is fitted to the rear end of the traveling cushion which moves to and fro with same so that no discomfort may be experienced by the patient in the operation of entering or leavingthe chair. I

lVhen it is desired to remove the patient 7 from the chair the sprocket gearingisturned in the required direction and the patient is brought to the front edge of the chair from which position the patient is then lifted with relative ease.

And in order that my invention may be fullyyunderstood I will now proceed to describe same with reference to the accompanying drawings andfigures and letters of reference marked thereon, that is to say Figure l is a side elevational view of-an invalid chair constructed in accordance with this invention, and showing same with the traveling cushion .in the positionrequired where the chair'is occupied, and

Fig. 2 is a similar view of the chair showing the traveling cushion brought to its forward position ready for the reception of the patient.

Similar letters of reference indicate like parts in both figures.

a is the ordinary spring stuffed seat of the chair, I) the back and c the arm rests. The chair is made sufliciently deep to permit of a person being seated therein with legs raised.

d is the traveling pneumatic cushion attached at its front ends to cords 6 (one of which is arranged at each side of the chair) which latter are connected to a roller f fixed upon the sprocket spindle g.

h is the operating handle'by which the chain wheel Z is turned and 7c is the chain drive passing over the Wheels Z and m. This forms a convenient mechanism for communieating the required movements to the traveling cushion d. The rear end of the cushion is connected by cords n (one upon each side of the chair) to the rollers 0 fixed on the spindle of the wheel Z.

The spindles of the wheels Z and m are carried across the p is an. auxiliary back attachedto the cushion d, sliding in guides 9 provided upon the chair and traveling backward and forward with the cushion (Z.

The back proper b of the chair is preferably recessed (see particularly Fig. 2) as at b to form a housingfor the auxiliary back p when the latter is in the rear-most position. a I

r is a foot rest slidingin guides formed in the side rails s of the chair, which is drawn out as shown in Fig. 2 when required for use, as for instance when drawn up to table.

The lengths of the "cord 0 and n are such as to permit of the required amounts of each to be wound upon their respective rollers to allow of the movement backward and forward of the cushion d in the chair.

In Fig. 1 the ends of the cords n are assumed to be wound on the roller 0 while the cord 0 is unwound from its roller 7 to its fullest extent. To draw the cushion from the position shown in this figure to that shown in Fig. 2 the handle it is turned in the forward direction, the cords n will consequently be unwound from the roller 0 while the cords 0 Will be woundon the roller j, the cushion (Z thus being drawn forward. To return the cushion to the position shown in Fig. l, the handle it is turned in the reverse direction. t and u are idle rollers for guiding the cords e and n. The chair is mounted on Wheels 41, and, to prevent acci- Oopies of this patent may be obtained for dental movement, the chair is fitted with a check or brake appliance w which conveniently consists of a dependent rod or tube a on, or in, which is a tube or rod y, terminating in a foot .2 which may be raised from, or lowered to, the ground by screwing or otherwise.

What I do claim as my invention and desire to secure by Letters Patent, is

1. In an invalid chair, the combination of a traveling cushion having an auxiliary back, cords connected at one end to the front and rear ends respectively of the cushion, rollers to which the other ends of the cords are connected, and an operating gear for winding and unwinding the cords on or from said rollers and thereby drawing the cushion backward and forward.

2. In an invalid chair, the combination of the traveling cushion (Z, cords e and 41,, rollers f and 0, drive wheels Z and m, operating handle h, the auxiliary back 77, sliding in guide rails q, the sliding foot rest r mounted in the side rails s, the idle rollers t, u, wheels 7), and brake mechanism substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
